Super Precision Angular Contact Ball Bearings S7009 FEGA/HCP4A

Super Precision Angular Contact Ball Bearings S7009 FEGA/HCP4A

The S7009 FEGA/HCP4A is a super precision angular contact ball bearing with a 45mm bore and 75mm outer diameter, crafted from chrome steel for durability. It features a sealed design and ceramic balls, ensuring smooth operation at high speeds up to 41,000 RPM.

With an 18° contact angle, it handles both radial and thrust loads effectively, supporting dynamic radial loads up to 2858 lbf. The phenolic cage adds strength while keeping the weight light at just 0.23kg.

Its extra light preload (Class A) and P4A tolerance class make it ideal for high-precision applications. Suitable for use in pairs, it can be arranged back-to-back, face-to-face, or tandem for versatile mounting options.

Perfect for CNC spindles or high-speed machinery where accuracy and reliability are key. Works well in temperatures from -30°C to 110°C and is interchangeable with SKF bearings for easy replacement.
